Application filed. March 2, 1910. Seria1 N0. 546,930.

T0 all whiwnit mag; Eoncem;

. Be it kn0wn that I, HENRY C. MILLER, a citizen of the Uni ted States, and resident 0f Milwaukee, in the"coimty 0f Milwaukee und State of Nisf:onsi11,fhave inv"ented certain 11ew and nseful Improv(aments in Loose-Leaf Binders; and I- do hereby declare that the following is a. full, clear, und exact description thereof.

My invention eonsists' in whut is herein particularly set forth with reference to the accompanying drawings and pointed out in claims of this specification, its object being to provide for ecz0n'omical construction of simple, durable and efficient temporary lock- 1ng and pe'rman'ent sealing loose-leai binders that areespeially designed for type-written perxnit ready r emval and inser' tion of leaves at either side of same prior to s ealing.

- Figure1 1 of the drawingS repre:aents a plan view, partly in horizontal seetion, of a bindet-frame of my an un10okinm key -anal a permanent seal ing plug being filustrated inthe same view detached from seid frame; Fig. 2, a similar view illustrating said plug caught in the frame, Fig. :a plan vi6w of a 0st locking slide of slightlydiflerent form 50m the one shown in Fi s. 1 and 2; Fig. 4, a rear eleva tion .of the inder-frame partly in section,

Fig. l; Fig, 5, a secti0nal view on theplnhe indicated by line 55-in Fig. 2; 'Fig. 6, a transverse ectional view of sa id frame indicated by line 6-6 in Fig. 2, -a bindet-back and cover being-illustrated by dotted lines in this view; F1g; 7, an end elevation of one ofthe*hollow bar members 0f the hinderframe, and Fig.' 8,.a transverse sectional view' of a fra ment of said fyame 011 the plane indicatec%by line 8.8 in Fig. 2.

Referring by numerals to the drawings 9 indicateseaeh of' a pair of hollow flat bar memb'ers, and 10%atch of the postmembers of a loose-leaf bindenframe embodying- 1ny 'members beingl, The bar-menr e1s of the frame are apertured at intefvsaxlis improvements, all of said 1gareferambly made frorn steel.

0f their length for the engagement 0f the preferably shouldered and slabbed ends of the Ost-members, and each post-member7isr pre erbly curg ed between its shoulders 11 that oppose theijnner sides of said baT-men'ibe1-s. As a nTatter of detail each bar-memeac h binder being eonstructed to improved construction,

ber is preferably composed of two fiat p ieces one of which has the edges thereof turned inwa rd to forinflanges 12 upon which toseeure the othe, dispo'sed spacin -ri'vets 13.

' The ends of each ost 10 are grooved in a direction longitudinally of the binder for the engagement of locking slides 14- run in the bars 9, eaeh slide being notched for automztti'c engag(arnnt Witha spring-controlled latch 15 p1voted- As herein show, each slide ispreferably arrow-pointed a one end to facilitate its engagement with a. latch regardless of which side of seid s1ide s up'permost When insert ed in a bar, the latph be1ng eaught back 0f a barb ofthe ar1pfv-point of the slide.

. The latch-end ,of each bar is eo ped by a guide 10 for a key 17 *of the a1e lock type, and in practice it is intended t0 indefinitely vary the grooving of the guides and keys' in orde r that a specially fitted key shall be required t0 retract the latches of eaclibinder.

of the bars 9 retracts the opposing latch against resistance of its controlling spring 18, t0 Permit withdrawal of a slide 14 tha.t is also pushed by seid key to clearthe opposts.--

Ether bar 9 majr be detached fro1n the s *sea1 the binder, a. sealing-p lug 20, sir ifilar to the one shown in Figs. l, 2 and 5is engaged from the key-guide 16 therewith. Each on both sides at one end adjacent 110 an aperturel 21 therein, tl1is aperture being for piece by means 0:E suitably the distangagement. of seid bar from both NITE ?ATENT OFFICE.

Pushing insertion of a properkeyin each posite end of seid bn. far enough to 108'85 zv 10 to permit of loose record leaves (not ho n) being put on 0r taken ofl the posts being desirable to permanently.

With each bar 9 in that end of Same farthe5t sealing-plug is a right-2Jngle plate beveled' engagement With a Ing 22 in the bar in Whidh tne piug driven to cIose an er'1d 0f same and thereby prevent retraction of the opposing slide, said Ing being preferably beveled, as best shbwn in Fig. 5, to facilitate locking engagement therewith 0f sai'd sealing-plug. When the sealing takes place the slide 14 is pushed in clea'r of the-lat ch 15 1atch in the aforesai d bar engageable with' the slide.

2. In a loose-leuf binder, apai1' of hollow bars apertured at intervals 0f their length,'

posts having detachable engagement with the bars through the apertures therein, a postengaging slide in each bar longitudinally 0f the same, and spring-controlled ey-release sli de-engaging latches in said ars.-

[3. In a loose-leaf binder, ahollow bar havi-ng a guide at 0ne end thereof for a key of the Ya1e lock type, posts.having detavhubl engag elnent with the bars, a postenguging .slide in Said bar, and a springcontrolled key-telease latch in the aforesaid bar engageable with fd1e slide.

4. In a loose-leaf binder, a pair of hollow bars euch having a guide :it one end thereof for a key 0f th Yale lock type, p osts having detachable engagenient with the bars,

a post engaging slide in each bar, and spring-controlled key-release slide-engaging latches in said bars.

5. In a looseleaf binder,a hollow bar that is closed at one end, posts having detachable engagement With the bar, a slide in said bar engaging grooves in the osts longitudinally f the binder, anda s1i e-opposingsealingplug insertible in end of ehe gforesaid bar.

G. In lo'ose-leaf binder, a 110110W bar provid ed at one end with an inner Ing, posts having detachable engagement with the bar, a post-engaging sli'de in said bar, and a slide opposing aperturd sealing plug insertible in the afoiesaid bar to engage said Ing of same, the other end of the bar being closed against withdrawal of the slide.

having a key'guide cap at one end thereof, posts having detachable engagement with the bar, a slide in said bar engaging grooves in the posts longitudinally of the binder, and a slide-opposixw sealing-plu insertible in the other end o? the aforesai b'ar.

8. In a loose-leaf binder, a pair of hollow bars, posts having detachable engagement with the bars, a slide in euch bar engaging grooves in the posts longitudinally of the binder, und a slide-opposing sealing-plug insertible in one endof each bar that. is'closed at its otherend against withdrawaI of the slide. v v

9. In a louse-leaf binder, a hollo\v bar, .posts having detaqhable engagement with the bar, a post-engaging slide in said bar, a spring controlled key'- relea'se latch in the aforesaid bar normally engageable with the slide, and a slide-op osing sealing-plug insertible in an end 0 the bar.

10.-In a l0Ose-leaf bindet, a hollow bar posts luwing detachable connection with the bar, an arrow-pointed slide in said bar engageable yvith grooves in the posts longitudinally of the bindet, und a Spring-coutrolled key-release latch in the aforesa1d bar engageable with the slide back of either barb of its point.

In -testirnony that I claim the foregoing I have hereunto set my band ab Milwaukee in th oounty of Milwaukee and Staoe of \Visconsin in the pr'esence of two witnesses.
